DUCHESS KATE WARNS NEW NEIGHBOR PRINCE HARRY: NO BOOZING!

Princess of Our Hearts KATE MIDDLETON warned badboy/bachelor brother-in-law PRINCE HARRY he’d better get a few things straight as he makes his big move into royal roost Kensington Palace, where she and PRINCE WILLIAM reside.

Kate decreed to party-hearty Harry that she will NOT tolerate late-night drinking sessions, and will take off-with-his-head offense if he pops into their private living quarters unannounced.

While Kate adores Harry, she feels he brings out the wild child in hubby Prince Charming, and admitted to pals she wasn’t thrilled when informed of his return to the home he’d shared in childhood with William and their mom, People’s PRINCESS DIANA.
